Tom Gundersen ab046dde6f nspawn: add new --network-bridge= switch
This adds the host side of the veth link to the given bridge.

Also refactor the creation of the veth interfaces a bit to set it up
from the host rather than the container. This simplifies the addition
to the bridge, but otherwise the behavior is unchanged.

Jason St. John b200a92cdc man: use spaces instead of tabs
Several sections of the man pages included intermixed tabs and spaces;
this commit replaces all tabs with spaces.

Zbigniew Jędrzejewski-Szmek 6db2742802 man: replace STDOUT with standard output, etc.
Actually 'STDOUT' is something that doesn't appear anywhere: in the
stdlib we have 'stdin', and there's only the constant STDOUT_FILENO,
so there's no reason to use capitals. When refering to code,
STDOUT/STDOUT/STDERR are replaced with stdin/stdout/stderr, and in
other places they are replaced with normal phrases like standard
output, etc.

Jason St. John bcddd5bf80 man: fix grammatical errors and other formatting issues
* standardize capitalization of STDIN, STDOUT, and STDERR
* reword some sentences for clarity
* reflow some very long lines to be shorter than ~80 characters
* add some missing <literal>, <constant>, <varname>, <option>, and <filename> tags

Dave Reisner 29e254f7f0 man: systemd.service(5): clarify behavior of SuccessExitStatus
The behavior of this is a little cryptic in that $MAINPID must exit as
a direct result of receiving a signal in order for a listed signal to
be considered a success condition.

Lennart Poettering d3b1c50833 core: add a system-wide SystemCallArchitectures= setting
This is useful to prohibit execution of non-native processes on systems,
for example 32bit binaries on 64bit systems, this lowering the attack
service on incorrect syscall and ioctl 32→64bit mappings.

Lennart Poettering 17df7223be core: rework syscall filter
- Allow configuration of an errno error to return from blacklisted

- Fix parsing logic when libseccomp support is turned off

- Only keep the actual syscall set in the ExecContext, and generate the
  string version only on demand.

Also limit the range of vlan ids. Other implementations and
documentation use the ranges {0,1}-{4094,4095}, but we use
the one accepted by the kernel: 0-4094.

Lennart Poettering 82adf6af7c nspawn,man: use a common vocabulary when referring to selinux security contexts
Let's always call the security labels the same way:

  SMACK: "Smack Label"
  SELINUX: "SELinux Security Context"

And the low-level encapsulation is called "seclabel". Now let's hope we
stick to this vocabulary in future, too, and don't mix "label"s and
"security contexts" and so on wildly.

Michael Scherer 0d3f7bb3a5 exec: Add support for ignoring errors on SELinuxContext by prefixing it with -, like for others settings.
Also remove call to security_check_context, as this doesn't serve anything, since
setexeccon will fail anyway.
2014-02-10 13:18:16 +01:00
Michael Scherer 7b52a628f8 exec: Add SELinuxContext configuration item
This permit to let system administrators decide of the domain of a service.
This can be used with templated units to have each service in a différent
domain ( for example, a per customer database, using MLS or anything ),
or can be used to force a non selinux enabled system (jvm, erlang, etc)
to start in a different domain for each service.

Lennart Poettering a4cd87e9dc man: introduce new "Desktop" property for sessions
This is initialized from XDG_SESSION_DESKTOP and is useful for GNOME
to recognize its own sessions. It's supposed to be set to a short string

Lennart Poettering d002827b03 nspawn: various fixes in selinux hookup
- As suggested, prefix argument variables with "arg_" how we do this
  usually.

- As suggested, don't involve memory allocations when storing command
  line arguments.

- Break --help text at 80 chars

- man: explain that this is about SELinux

- don't do unnecessary memory allocations when putting together mount
  option string

Dan Walsh a8828ed938 Add SELinux support to systemd-nspawn
This patch adds to new options:

-Z PROCESS_LABEL

This specifies the process label to run on processes run within the container.

-L FILE_LABEL

The file label to assign to memory file systems created within the container.

For example if you wanted to wrap an container with SELinux sandbox labels, you could execute a command line the following

chcon system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -R /srv/container
systemd-nspawn -L system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -Z system_u:system_r:svirt_lxc_net_t:s0:c0,c1 -D /srv/container /bin/sh

Tom Gundersen eb27aeca24 networkd: dhcpv4 - add notion of 'CriticalConnection'
These connections are never torn down, even when the DHCP specifications say that
they should be. This is useful/necessary when the rootfs (or another critical fs)
is mounted over this network connection, and dataloss would result if the connection
is lost.

This option defaults to off, but our initrd generator (TBD) will enable it when
applicable.

Lennart Poettering 58ea275a68 core: introduce new KillMode=mixed which sends SIGTERM only to the main process, but SIGKILL to all daemon processes
This should fix some race with terminating systemd --user, where the
system systemd instance might race against the user systemd instance
when sending SIGTERM.

Zbigniew Jędrzejewski-Szmek d450b6f2a9 manager: add systemd.show_status=auto mode
When set to auto, status will shown when the first ephemeral message
is shown (a job has been running for five seconds). Then until the
boot or shutdown ends, status messages will be shown.

No indication about the switch is done: I think it should be clear
for the user that first the cylon eye and the ephemeral messages appear,
and afterwards messages are displayed.

The initial arming of the event source was still wrong, but now should
really be fixed.

Zbigniew Jędrzejewski-Szmek 65b3903ff5 journal: guarantee async-signal-safety in sd_journald_sendv
signal(7) provides a list of functions which may be called from a
signal handler. Other functions, which only call those functions and
don't access global memory and are reentrant are also safe.
sd_j_sendv was mostly OK, but would call mkostemp and writev in a
fallback path, which are unsafe.

Being able to call sd_j_sendv in a async-signal-safe way is important
because it allows it be used in signal handlers.

Safety is achieved by replacing mkostemp with open(O_TMPFILE) and an
open-coded writev replacement which uses write. Unfortunately,
O_TMPFILE is only available on kernels >= 3.11. When O_TMPFILE is
unavailable, an open-coded mkostemp is used.

Christian Seiler b4a11878f2 cryptsetup: Support key-slot option
Debian recently introduced the option key-slot to /etc/crypttab to
specify the LUKS key slot to be used for decrypting the device. On
systems where a keyfile is used and the key is not in the first slot,
this can speed up the boot process quite a bit, since cryptsetup does
not need to try all of the slots sequentially. (Unsuccessfully testing
a key slot typically takes up to about 1 second.)

This patch makes systemd aware of this option.
